Cause:
The minimum and maximum voltage readings (Vmin/Vmax) do not get transmitted from the UPS when connected with the SUA Smart-UPS via USB cable. These values are filled in when the same UPS is connected via the 940-0024C or 940-1524C serial communications cable. This is a limitation of USB communications on a Smart-UPS SUA model UPS. The current voltage at the time the data is being recorded does populate with the correct information.

Also, the The minimum and maximum voltage readings (Vmin/Vmax) do not get posted to PCBE when attached to Microlink Smart-UPS.
